[Development] Qt 5.12 schedule proposal & proposal for release process change

Hi,

I very much like continuous flow of snapshots. Sometimes we have a tendency to fall into a "let's wait and get still this one fix in" mode, which is very inefficient. It is beneficial when making .x patch releases and the fix is for a regression. But in other situations, it is typically more important to have a frequent flow of releases. From that viewpoint I support what Jani proposed. Every period of wait we add makes the release process: 1. longer and 2. unpredicted. We should aim to make the process of creating a new feature release of Qt faster than it is today, so challenging the current process is a good thing. 

We are working on enabling regular snapshots from dev, with target of moving more development and interoperability testing to dev (and thus adding the maturity of dev, making it easier to develop with etc). After these are in place, we have snapshots rolling from all branches of a release. 

With dev snapshots in place, I agree with Jani and think we could:
- Discontinue the concept of an 'Alpha' release of a new Qt version starting from Qt 5.12 (in a way every dev snapshot is a pre-release of Qt 5.12)
- After branching to 5.12, call the first released snapshot Qt 5.12 Beta 1 (or use build number)
- After branching to 5.12.0, call the first released snapshot Qt 5.12 RC 1 (or use build number)

With this we would focus the activities more into moving to a new branch - and of course keep (and even improve) the existing criteria when we are ready to branch. Use of build numbers instead of Beta 1 etc is also fine for me, if preferred.

Yours,

		Tuukka

    Hi,
    
    Same here. At first this seemed like a good idea, but it becomes awkward when you look at it from the dev workflow point of view: After fixing a bug, what is the fix version? Reported in snapshot-24062918 and fixed in snapshot-14072918? That sounds like it would create a mess in JIRA.
    
    Unless of course the task of assigning the fix version field was automated.

The distinction may not make a difference from the release team perspective but it makes a world of difference for developers (who have different limitations for each step) and the world as they can decide how bleeding edge the code is that they want to test.
